It's designed specifically for RG-108A cable, a twinaxial cable type common in video distribution, data networks, and instrumentation runs that need a shielded differential pair. The connector body carries both a female socket and a male pin, which is the twinaxial interface: one conductor routes through the center pin, the other through the surrounding socket, all inside a 50-Ohm-ish geometry that holds up to 4 GHz. The bayonet lock gives the same quarter-turn mate as a standard BNC, so it's field-friendly with no tools beyond the crimp hex for the shield termination. ## What You Get in the Kit This is a field-assembly kit, not a bare connector shell. The package includes four pieces: the connector body with the contact assembly pre-loaded, one ferrule, and one insulator. The ferrule crimps over the braid shield, the insulator sits between the center conductors, and the contact assembly solders to the twinaxial wires. The kit covers everything needed to terminate one end of an RG-108A cable. The brass body wears a nickel finish — standard for BNCs that see outdoor or industrial use — and the center contacts are gold-plated for corrosion resistance across the rated 500 mating cycles. ## Weatherproof Rating and Operating Range This connector carries a weatherproof ingress protection rating, which means the bayonet lock and internal gaskets seal the interface against moisture and dust when mated with the corresponding jack. It's not a full IP67 submersible — it's weatherproof for outdoor cable runs, not for washdown or immersion. The dielectric is PBT, a common thermoplastic for RF connectors that holds up well in that temperature range without significant dielectric loss shift.","metaTitle":"Amphenol 162108B BNC Twinaxial Plug, RG-108A, 4 GHz, 500 V","metaDescription":"Amphenol 162108B BNC twinaxial plug for RG-108A cable. 4 GHz max frequency, 500 V rating, weatherproof, bayonet lock.
